Specification of Letters Patent.

Patented March 12, 190-7.

Application filed November 28, 1906. Serial No. 345,443.

To all whom it may concern:

Be it known that I, HALsEY W. RUssELL, a citizen of the United States,and a resident of Manchester, in the county of Hillsboro and State ofNew Hampshire, have invented a new and Improved Sad-Iron Heater, ofwhich the following is a full, clear, and exact description.

TlllS invention relates to heaters designedto heat sad-irons, and hasfor its object to provide a gas-heater which is simple in construction,effective in operation, adapted to be used with the least possibleexpenditure of gas, to render the use thereof absolutely safe under allconditions, and to enable the heater to be used without generating theoffensive odor common to devices heretofore used for the same generalpurpose. 1

Such objects I accomplish by the means illustrated in the accompanyingdrawings, in which drawings like characters of reference indicate likeparts throughout the views, and in which Figure 1 is a centrallongitudinal section, partly in side elevation, of a device embodying myinvention, with a sad-iron shown in side elevation attached thereto.Fig. 2 is a vertical section of the device shown in Fig. 1, taken on theline 2 2 of said figure. Fig. 3 is a vertical cross-section taken on theline 3 3 of Fig. 1. Fig. 4 is a vertical cross-section taken on the line4 4 of Fig. 3. Fig. 5 is a vertical cross-section taken on the line 5 5of Fig. 1. Fig. 6 is a side elevation of the end of the heater, and Fig.7 is a plan view of the part shown in Fig. 6.

As illustrated in the drawings, the main frame or casing 1 of the heateris provided with a clamp 2, having an offset arm 3, which is providedwith a fastening thumb-screw 4, adapted to be attached to the ledge of atable 5 or other suitable object, so as to hold the heater fixedlysecured in position. The back end 6 of the main frame is flared or madeconical in outline and adapted to receive a correspondingly-shaped headof a sleeve 7, which is rotatably mounted in the casing 1. The end ofthe sleeve is provided with sectorplates 8, spaced at their inner ends,so as to form a central aperture 9 in the end of the sleeve shown inFig. 1, and otherwise corresponding in general outline with anadjustinglate 10, secured to the end of said sleeve, as s1own in Fig. 2.The adjustinglate 10 is provided with sector-plates 11, W 'ch areconnected together at their inner ends by means of a central disk 12.The adjustingplate 10 is also provided with apertures 13, by means ofwhich and the engaging-screws 14 the plate 10 may be adjusted on the endof the sleeve, so as to reduce the area of the openings 15, formed insaid plate and in the end of the sleeve on opposite sides of thesector-plates 8 and 11, respectively.

The flaring end of the sleeve forms a mixing-chamber, and by adjustingthe plates 11 on the end of the sleeve, so as to regulate the extent ofthe apertures 15 formed therein, the supply of air passing into themixingchamber is thereby regulated. A gas-cock 16 is fixedly secured tothe main frame of the heater and is provided with a shank 17, the end ofwhich extends through the adj ustingplate 10 and end of the sleeve andis provided on its inner end with a tip 18, (shown in Figs. 1 and 5,)which is provided with an orifice 18 adapted to supply gas to themixing-chamber.. The tip 18 is adjustably secured to the shank of thesaid gas-cock, so that tips having orifices of different diameters maybe applied thereto to compensate for the pressure in the mains and inthe pipes to which the burner is connected. The shank of the gas-cock isprovided with a controlling-lever 19, which is arranged in line with theheads of the screws 14, so that when the sleeve is rotated one of thescrews 14 will come in contact with the controlling-lever 19 of thegas-cock and shut off or turn on the supply of gas to the mixing-chamberin accordance with the direction in which the sleeve is rotated in thecasing or main frame 1. The sleeve 7 may be provided with a collar 20,fixedly secured thereto in any suitable manner, preferably by means of ali 21, formed on said collar, which is detac ably secured by means of ascrew. 22 to a burner 23, formed integral with the sleeve 7 andextending from the end of the main frame or casing outward. The burner23 is provided on one side with orifices 24 and on the opposite sidewith a longitudinal groove 25, adapted to engage a projection 26, formedon the upper portion of a sad-iron 27, as shown in Fig. 5.

The burner 23 is provided with a reduced end 28, having substantiallyparallel sides and an inclined edge 29, adapted to engage acorresponding aperture formed in the front end of a sad-iron, asindicated by dotted lines in Fig. 1. The collar is provided with a lug21*, (shown in Figs. 3 and 4,) which is adapted to bear against asector-flange 30,

formed on the main frame or casing of the burner, as shown in Fig. 3. .Acircular spring 31 is secured to the flange 30 by means of a set-screw32 and is provided with offset ends 33, adapted to retain the lug 21 ineontact with the end of the sectonhange 30, as 1 shown in Fig. 3, so asto lock or retard the rotary motion of the burner relatively to the mainframe.

Vhen the device is in operation, the burner is attached to a table,shelf, or other object in the manner already described and is connectedto a supply-pipe by means of a flexible tube 34, which supplies gas tothe burner. A sad-iron is applied to the burner when the groove 25,formed therein, is arranged uppermost. When in such position, theorifices 24 of the burner are arranged at the lower portion of theburner, as shown in Fig. 1, and the supply of gas to the burner isreduced, so as to merely keep the burner lighted. After the sad-iron hasbeen. thus applied to the burner the iron is turned through half arevolution, and by means of the locking connection with the burnerhereinbefore described the burner and sleeve, formed integral therewith,are rotated in the casing, through half a revolution, and during suchrotary movement of the sleeve the studs or screw-heads 14 come incontact with the operating-lever 19 and open the gas-cock, so as toallow the full supply of gas to be admitted to the mixing-chamber andburner. When the sad-iron has been rotated in the manner described andthe gas turned on to its full extent, the orifices 24 and the fiamesextending therefrom are arranged at the up per portion of the burner,and the sad-iron is supported on the burner bottom side up, as indicatedby dotted lines in Fig. 1. After the iron has been sufficiently heatedthe operation is reversed and the iron turned through half a revolution,which brings the handle of the iron uppermost, as shown in Fig. 1, atthe same time, partially rotating the burner and sleeve formed integraltherewith, so as to shut off the supply of gas to its minimum limit, andthe sad-iron may then be readily removed from the burner and used.

While the sad-iron is on the heater it is held against lateral or rotarydisplacement on the heater by means of the lug 25, engaging alongitudinal groove formed on the heater on the side opposite to theorifices 24. In addition to locking the sad-iron against rotary motionon the burner said interlocking means furnishes a guideway for thesad-iron when being applied. to or removed from the burner.

The construction and arrangement of the device, therefore, is such thatwhen the iron 1 is removed from the burner the supply of gas is reducedto an amount sufficient to keep the 1 flarrfes alive, and the flames arearranged on the under side of the burner, so as to be safely out of theway of the person using the device. The supply of gas is turned on toits full extent and is operative only when the sad-iron is supported onthe burner bottom up.

In the construction herein shown and described I have embodied myinvention in a preferred form. I do not desire to be limited to suchconstruction, however, as my invention is generic in its character andincludes within its scope other means having similar capabilities. Thusthe spring mech anism which looks or retards the burner against rotarymotion relatively to the main frame may be of any other suitableconstruction than that shown and applied to the sleeve or connectingmechanism in any 'position, and any other suitable form of burner ormixing-chamber may be used with the other features of my device withoutdeparting from the scope of my invention.
